The present application discloses an array substrate comprising a base substrate, a row of a plurality of pixel units, and a first gate line and a first common electrode line adjacent to the row of the plurality of pixel units and on a first side of the row of the plurality of pixel units in plan view of the array substrate. The first gate line and the first common electrode line are spaced apart by a gap; and a light shield at least partially covering the gap for reducing light leakage from the gap.
